MEANS FOR SUPPORTING AND LEVELING BRAKES.

Specification of Letters Patent. Patented Mai. 30, 1920.

Application filed July 29, 1918. Serial No. 247,098.

To all whom it may concern:

Be it known that I, AR ANI) H. Parents,

a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and use ful Improvements in Means for Supporting and Leveling Brakes, of which the following is a specification.

This invention relates to means for supporting and leveling brakes, and more particularly to a third point supporting arrangement.

The object of this invention is to simplify and improve brake supporting and leveling means, and to provide an improved arrangement that will meet the requirements for successful commercial operation.

This and other objects are accomplished by the arrangement shown on the accompanying sheet of drawings, in which Figure 1 is a fragmentary side elevation, parts being in section, of a railway car truck embodying my invention.

Fig. 2 is a fragmentary plan view of the same arrangement.

Fig. 3 is a detail plan view of a modified form of my invention.

Fig. l'is a detail view of the same parts shown in Fig. 3 taken at a different angle, and I Fig. 5 is a side elevation of the members shown in Figs. 3 and 4.

The various novel features of my invention will be apparent from the following description and drawings, and will be particularly pointed out in the appended claims. I

Referring to the figures of the drawings, it will be noted that I have shown my invention in connection with a railway car truck, including a spring plank secured to opposite sides of which at each end are combined safety bar brackets and brake beam supporting and leveling'members 11. Preferably each of the members 11 has. a hooked portion which passes over a vertical flange of the spring plank 10, in addition to being riveted to the spring plank. The lower portions of these members 11 preferably are apertured for the reception of safety bars 12 which underlie the brake beams for the purpose of preventing the brake beams from falling to the track in the event that they become detached from their normal hangings. The safety bars have spring clips 13 which engage the bracket members It will be understood that the brake beams normally are held at a pre-determaintained in concentric relationship with respect to the braking surface of the associated truck wheel. I

' By referring to Fig; 2, it will be noted that I have shown four of the combined bracket and supporting members 11, the overhanging portions let of which extend outwardly from the spring plank 10 to a erum 18 in each case. By referring particularly to'Figs. 1 and 2, it will be noted that the associated lipped ends 19 of the resilient members 14 are connected by a bar or. rod20, which is operatively' connected with the front end of the fulcrum 18 for the purpose of balancing the brake beam. The means for operatively connecting the rod20 to the fulcrum 18 may be varied. My preferred form is shown in Figs. 1 and 2. wherein the member 20 which extends transversely with respect to the car truck, or in the same direction as the brake beam, slopes downwardly from its outer ends to its mid dle point, at which point there is formed an integral eye portion 21, which is received between the jaws 22 of the fulcrum 18. Through these jaws and through the eye 21 there passes a connecting pin 23. I In this manner the brake beam is retained in a balanced condition in a simple manner, the rod 20 acting as a swinging link which is yieldably supported. 4

In Figs. 3, 4, and 5, I have shown another It is well appreciated,

point in line with the front end of the fulrod 24 which may be substituted for therod 20 shown in Figs. land 2, this present rod 24 also extending downwardly towardits center portion and instead of being con- 1.

nected directly to the fulcrum passes through an aperture 25 in a link aerating another aperture 27, by means of which the link may be connected to the fulcrumby a:

suitable pin.. If desired, the dip of the rod 24: may be increased at its middle point 'to, such an extent that the rod itself mightpa-ss through the apertures in the fulcrum jaws. .There may be other modifications of the invention, and it is my intention to coverall such modifications falling within the Spirit and scope of the following claims.

What I claim is:

1. In brake mechanism, the combination of a brake beam, and a member extending in the same direction as the brake beam and having a downwardly extending portlon operatively connected to said brake beam at anintermediate the latter. a

2. In brake mechanism, the combination point thereof for supporting of a brake beam, a resilient member extending over sald brake beam, and a men; ber connected to said reslllent member and extending in the same direction as the brake beam and being operatively connected to the latter at an intermediate point thereof for holding the brake beam in a balanced position.

3. In brake mechanism, the combination of a brake beam, oppositely arranged'meln f bers located intermediate the ends of the; brake beam and extending transverselyoVer' the latter, and a member connected tosaid oppositely arranged members and being op? eratively connected to the brake beam for supporting the latter in a balanced position,"

4. In brake mechanism, the combination of a brake beam having tension and compres -s1on members, a fulcrum connecting same,

and a member extending in the same 'direm tion as the brake beam and having a down-j wardly extending portion operatively con nected to the fulcrum for supporting the brake beam in a balanced position.

5. In brake mechanism, a brake beam supof the truck to the other and having intermediate its ends an eye portion operatively connected to the brake beam for supporting a the latter.

6. In brake mechanism, the combination of a brake beam having tension and'compression members, a fulcrum extending therebetween, and a member extending transversely of the car supported at more than one point and having an eye portion operatively connected to the fulcrum memher for balancing the brake beam.

-, '7.- In brake mechanism, the combination of a brake beam, asupported bracket mem ber, asafety bar connected tosaid bracket member and underlying the brake beam, 1 said bracket member having a portion overhanging said brake beam, and a member connected to the overhanging portion and extendin in the same direction as the brake beam and having a portion operatively connected to the brake beamfor supporting-the latter.

8. In brake mechanism, the combination of a brake beam, a safety bar underlying the brake beam for preventing the latter from falling'to the track, a member connected to the safety bar and extending over the brake beam, and means supported by said member andextending in the same direction as the brake beam and having a portion operatively connected to the brake beam to hold -the latter in a balanced position.

9. In brake mechanism, the combination of a brake beam, safety bars underlying the "brake beam near the opposite ends thereof,"a .fplurality of spaced members extending over j 'said brake beam and connected to the safety bar, and a member connected to said spaced ,;members and havinga portion operativelyf connected to the brake beam for supporting the latter.
